Princess Beatrice's baby daughter Sienna could be seen showing a glimpse of her red auburn hair in a new snap of the late Queen Elizabeth II.The image was a posed family portrait with the monarch and her young grandchildren and great-grandchildren in the latter days of her life. A few of the great-grandchildren were unfortunately missing from the monumental snap - in particular the Duke of Sussex Prince Harry's children Prince Archie, three, and Princess Lilibet, one, Princess Eugenie's son August Brooksbank, and 34 year old Princess Beatrice's daughter Sienna, who would have been one at the time.
